Actually the plans for the LJ are pretty opposite of all the rigs I have had in the past. When my wife and I took the toyota to moab we enjoyed the exploring more than the hardcore stuff.
That said, the plan for the LJ is a low cog with moderate tires (33-35) and some of the parts I kept from the toyota. We have been doing the body damage 37+ inch tires type trails for about 8 years so it will be interesting to take a different look at 4 wheeling.
If you look at UltimateCC's build thread that is very similar to what I have in mind for my new rig
